The City of Oak Ridge Public Works Department continues to utilize state-of-the-art technology to perform inspections of the City’s sewer system. This technology employs a sonar machine that emits a repeating series of tones, similar to a musical scale and in open areas can be heard over long distances. The tones emitted by the machine, while harmless, are low enough in frequency that residents nearby may be able to feel, and in some instances hear them.

Testing is ongoing, but will be concentrated to the following areas depending on weather constraints and other factors during the week of August 3. This includes the area between Fairbanks Road and Melton Lake Drive below the Turnpike, and Arcadia Lane and New York Avenue above the Turnpike. Residents will notice signage posted on main roads stating, “Acoustic Sewer Inspection in Area” while crews are working in their neighborhoods.
